Subject: Blitz Installed with Borland C++ Builder
Date: Tue, 15 Oct 2002 13:24:27 +0100
Organization: University of Oxford
[...]
Following your "Testing a compiler" instructions, I easily managed to
install Blitz for my Borland C++ Builder 5.0 (my updated BCC32.EXE
reports version 5.5.1) under Windows 2000 and Cygwin 1.3, so I am
attaching the resulting CONFIG.H to this email, as you suggested.
I also had to make slight changes in a couple of files, the two most
important being the following:
1. BCB doesn't like lines like
using T_base::data_;
using T_base::base_;
etc., inside the class declarations; the compilation actually results in
a "fatal internal error". Simple commenting out of these lines prevents
the error (only six header files seem to be affected by this).
2. All math.functions with complex arguments in MATHFUNC.H require a
reference to the data rather than just a copy; here is an example error
message:
[C++ Error] mathfunc.h(2394): E2357 Reference initialized with
'complex<float>', needs lvalue of type 'complex<float>'
and the solution is simply
{ return BZ_CMATHFN_SCOPE(abs)((complex<float>&)x); }
instead of the original
{ return BZ_CMATHFN_SCOPE(abs)((complex<float> )x); }
Similar problem occurs in class _bz_update:
{ x = (X)y; }
but changing it to
{ x = (X&)y; }
causes another problem with the floating-point types, so I had to
introduce a trait there (the default is the reference-cast which works
for any user-defined types as well as for all integer types).
The last comment I'd like to make here (to keep it brief) is a possible
mini-bug (next time I will report bugs directly to the bug-report email
address):
ostream& operator<<(ostream& os, const Array<T_numtype,N_rank>& x) fails
inside the iterator-loop when outputing tensors like 1x0x0, 1x1x0, etc.
(not 0x0x0); a simple check on size() after outputing the tensor
dimensions helps to possibly skip that loop (I am aware that
0-dim.tensors don't make too much sense and that's perhaps why you
didn't even consider them there - but you can create them:
Array<float,3> tnsr(1, 0, 0); ).
Thanks for Blitz and good luck with its future extensions and
improvements!
Radek
PS: I don't expect any reply to this email - I can imagine you get lots
of these...
